There have been many examples over the last decade of great and innovative ideas and products (the Apple revolution with the iPhone and iPAD springs immediately to mind). There have also been many examples of established ways of doing things being cast aside in the name of progress when the reality was that the established way of operating were perceived by some as being too restrictive or simply too hard.
For instance the fundamental rules of business were ignored during the dot com revolution. Fundamentals such as comprehensive business plans were replaced by fancy PowerPoint decks. Focusing on a path to profitability was frowned upon as being so old economy in the new era where businesses were driven by concepts and ideas rather than spreadsheets.
